Data protection frameworks worldwide, including the EU GDPR, UK GDPR, India’s DPDPA, UAE PDPL, and Swiss FADP define specific roles to structure personal data processing responsibly. These roles—Controller, Processor, and Data Subject—set clear responsibilities and ensure a rights-focused approach to data handling.

Data Controller

The Data Controller is the entity that determines the purpose and means of processing personal data. Controllers are accountable for compliance with data protection laws and for ensuring the protection of individuals’ rights.

• Example: A social media company deciding how users’ data will be used for targeted advertising and content recommendations is the Data Controller.

Terminology

• EU/UK GDPR: Data Controller
• DPDPA (India): Data Fiduciary
• UAE PDPL: Data Controller
• Swiss FADP: Data Controller

Joint Controllers

Joint Controllers arise when two or more entities collaboratively determine the purposes and means of data processing. They share responsibilities and must define their obligations transparently.

• Example: An airline and a hotel chain jointly managing a loyalty rewards program and deciding together how customer data will be processed are Joint Controllers.

Terminology

• EU/UK GDPR: Joint Controllers
• DPDPA (India): Not explicitly defined but implied in collaborative data-sharing arrangements.
• UAE PDPL: Joint Controllers
• Swiss FADP: Joint Controllers

Data Processor

A Data Processor is an entity that processes personal data on behalf of the Controller and under its instructions. Processors are responsible for ensuring secure processing but do not make decisions about the purposes of processing.

• Example: A payment gateway service processing transactions for an e-commerce platform acts as a Data Processor, following the platform’s instructions on handling customer payment data.

Terminology

• EU/UK GDPR: Data Processor
• DPDPA (India): Data Processor
• UAE PDPL: Data Processor
• Swiss FADP: Data Processor

Data Subject

The Data Subject is the individual whose personal data is being processed. Data protection laws are designed to uphold the rights of Data Subjects, including access to their data, correction, deletion, and restriction of processing.

• Example: A customer registering for an online health portal and sharing their medical history is the Data Subject, with full rights over their data under applicable laws.

Terminology

• EU/UK GDPR: Data Subject
• DPDPA (India): Data Principal
• UAE PDPL: Data Subject
• Swiss FADP: Data Subject

Additional Roles

Consent Manager (DPDPA, India): A role unique to India’s DPDPA, enabling entities to facilitate the management and tracking of user consent.

Data Protection Officer (DPO): A mandatory role under GDPR for certain entities, responsible for monitoring compliance and advising on obligations. Optional under UAE PDPL, Swiss FADP and DPDPA depending on processing scope.

Frequently Answered Questions

What is the difference between a Data Controller and a Data Processor?

A Data Controller decides the purposes for which personal data is processed, while a Data Processor processes data on behalf of the Controller according to their instructions. The Data Processor does not have control over the purpose of the data processing.

What is the role of a Data Protection Officer (DPO)?

A Data Protection Officer (DPO) is responsible for ensuring an organization’s compliance with data protection laws. They monitor the organization’s data processing activities, advise on data protection obligations, and act as a point of contact for both regulatory authorities and data subjects. The DPO role is mandatory under GDPR and DIFC laws for certain entities but is optional under UAE PDPL and India’s DPDPA, depending on the scope of processing.

What is a Consent Manager, and why is it important under India’s DPDPA?

A Consent Manager is a role unique to India’s DPDPA, responsible for managing and tracking user consent for data processing activities. This role ensures that data processing aligns with the individual’s consent preferences.

What rights does a Data Subject have?

A Data Subject has several rights under data protection laws, including the right to access their data, the right to rectify or delete their data, and the right to limit or restrict the processing of their personal information. These rights are aimed at giving individuals control over how their data is used.
